Round Fine Air Diffuser with ballast drawstring bag:

This fine small air diffuser will work with an air pump for aerating your pond in the summer and as a deicer in the winter months.

For Summer use: The Diffuser will work best when placed at the center in the deepest part of the pond in summer. The rising bubbles will lift and aerate bottom water, allowing oxygen to penetrate sediments and optimize waste decomposition. This will also keep stagnant deoxygenated layers from forming deep in the pond, and effectively circulate the entire pond if properly sized. The Ring Diffuser flowing one cubic foot per minute at 8' of depth will effectively aerate up to a 50 foot diameter pond; the shallower the pond, the less diameter can be circulated effectively.

For Winter use: Your Diffuser is ideal for keeping a hole open in ice during winter, but the Diffuser should NOT be placed in deep water. Rather, place the Diffuser in weighted Ballast Bag in no more than 16" of water at perimeter of pond farthest from deep end or deepest pocket. This will ensure that the circulation from the Diffuser will not supercool the water, which is warmest in the deepest part of the pond.
